The mold industry is the basic industry of the national economy , and is internationally recognized as a key industry . Mold forming with high efficiency , good quality , save raw materials , products and low cost , using a mold manufacturing products parts have become industrial production process means . In recent years, the introduction of finite element simulation method greatly improved mold design capabilities , it shorten the cycle , and reduce the number of test punch , reduce the cost of the product is of great significance . This paper introduces a stamping mold research at home and abroad in recent years the status quo and the development of dynamic , sheet metal forming simulation and springback development and current status of some of the key technical issues and applied research in -depth study . A thin-walled parts of the military enterprises for the study, parts of complex shape , fold phenomenon often associated with its deep drawing process . According to the basic theory of the structural features of the part and mold design , design a stamping drawing die , to solve the folds in the forming process . Based on the structural characteristics of the mold , the CATIA software , including sheet metal , punch , three-dimensional model of the die , pressure parts board as well , including the blank holder ; finite element analysis software ANSYS / LS-DYNA as a research tool , numerical simulation method , a thin-walled parts , deep drawing and springback process . Obtained through the simulation of deep drawing of thin-walled parts and rebound process equivalent stress field in the deep drawing process , the equivalent strain field , as well as the thickness of the sheet metal changes , different friction coefficients and forming speed the result of the forming , shaping force , as well as the energy situation are compared and analyzed ; springback results on different materials and under different forming speed . The simulation results show that the mold structure design is a good solution to a thin-walled parts fold phenomenon . Springback simulation of deep drawing , simulated results, the rebound of the location and the amount of springback so that , when in actual production mold can advance compensation applications in production practice better .
